Throughout summer, this classic cottage garden perennial, produces masses of large, bell-shaped white flowers that form in clusters on the upright stems. This is a reliable and easy to grow plant, that will reward you with a long season of interest, particularly if the spent flowers are cut back. This is a great plant, well deserving of a place in the border.

Garden care: Protect the tender foliage from slugs and deadhead regularly to prolong flowering. Apply a generous 5-7cm (2-3in) mulch of well-rotted compost around the base of the plant in spring. Stake with bamboo canes or brushwood in spring before the flowers appear.
